Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an air conditioner, and more particularly to a device for attaching and detaching a dustproof air filter.

[Conventional technology]

3 to 6 are a front view, a sectional view and a perspective view of a main part showing a conventional air filter attaching / detaching device disclosed in, for example, Japanese Patent Application No. 63-104762, in which (1) is an air conditioner. A main body of the air conditioner, a front panel mounted on the front of the main body of the air conditioner (1), (3) an air inlet provided on the front of the front panel (2), and (4) a front panel ( At the air outlet provided on the right side of 2), the room air sucked from the air suction port (3) by the blower (5) is transferred to the heat exchanger (6) in the air conditioner body (1). Heat is exchanged and blown out from the air outlet (4).

(7) is a dustproof filter, which is provided with a projection A (8) and a projection 8 (9), respectively. (10) is the handle on the lower edge. Reference numeral (11) is each guide rail of the air filter (7), and (2a) and (2b) are an insertion port and a storage portion of the air filter (7), respectively. Reference numeral (12) is an attachment / detachment lever of the air filter arranged on the back surface of the front panel (2), and along the guide groove (3a) provided in the lower portion of the air suction port (3),
As shown in FIG. 3, the device is slidable in the left-right direction.

The attachment / detachment lever (12) is provided with an inclined portion (13) in each of the two notches and a locking portion (15) forming a hook portion with the protruding piece (14) in the one notch, and further the operation knob. (16) is integrally formed at one end and is arranged so as to protrude from the front panel. In addition, at the lower part of the air filter (7), the protrusion A (8) and the protrusion B (9) are engaged with and retained by the inclined portions (13) and the retaining portion (15), respectively. It is installed in.

Next, the operation will be described.

First, the air filter (7) is inserted into the storage portion (2b) from the air filter insertion opening (2a) upward. At this time,
In FIG. 5, each protrusion A of the air filter (7)
(8), B (9) abut on the lowermost part of the inclined part (13) of each notch of the attachment / detachment lever (12), and when pushed further upward, the attachment / detachment lever (12) has these inclined parts A (13). A horizontal component force moves to the right in the figure along with, and the protrusion B (9) fits into the locking portion (15) of the attachment / detachment lever (12) and is locked. The air filter (7) is thus set on the front panel (2).

Next, when removing the air filter (7), the protrusion B (9) of the air filter (7) is moved by moving the operating lever (16) in the direction of the arrow in FIG. When the detachable lever (12) is further moved in the direction of the arrow after being disengaged from the engaging portion (15) of the protruding piece (14) of the air filter (7), the protruding portion A (8) of the air filter (7) is detached (12). (3) is engaged with the slanted portion (13) and moves the air filter (7) downward along the slanted portion (13) while sliding. By this process, the handle (1
Since 0) projects and descends to the air outlet (4) of the front panel (2), the operator can take out the air filter (7) by pinching the handle (10).

[Problems to be solved by the device]

Since the conventional air filter attachment / detachment device is configured as described above, the attachment / detachment lever bends due to warping or its own weight, etc., and therefore the operability is poor due to the frictional resistance between the surfaces of the air filter and the attachment / detachment lever when attaching or detaching the air filter There was a problem such as.

The present invention has been made to solve the above problems, and an object thereof is to obtain an air filter attaching / detaching device with further improved operability when attaching / detaching the air filter.

[Means for Solving the Problems]

The air filter attaching / detaching device according to the present invention is provided with a plurality of concave or convex portions on the bottom surface of the air filter attaching / detaching lever.

[Action]

In the air filter attaching / detaching device according to the present invention, the operability at the time of attaching / detaching the air filter can be further improved by providing the bottom surface of the attaching / detaching lever with a plurality of concave surfaces or convex portions.

[Example of device]

An embodiment of the present invention will be described below. (1) ~
(16) is the same as the configuration of the above-mentioned prior art, and in FIG. 1, (17) is a concave surface and is provided at a plurality of places on the bottom surface of the attachment / detachment lever (12) of the air filter (7).

Next, the operation of the embodiment will be described.

First, when housing the air filter (7) in the front panel (2), the air filter (7) is inserted upward from the insertion port (2a) of the air filter (7). At this time, the surface of the air filter (7) is stored in contact with the surface other than the concave surface (17) provided on the bottom surface of the attachment / detachment lever (12). The following is similar to the above-mentioned conventional technique. When the air filter (7) is taken out from the front panel (2), the handle portion (10) of the air filter (7) is projected to the air outlet (4) of the front panel (2) and is lowered. Similar to the above-mentioned conventional technique, the surface of the air filter (7) has a detachable lever (12).
Is taken out while contacting with a surface other than the concave surface (17) provided on the bottom surface of the.

In the above embodiment, the detachable lever (12) is provided with a plurality of concave surfaces (17) on the bottom surface, but as shown in FIG. 2 in another embodiment, the detachable lever (12) is provided on the bottom surface. Even if a plurality of convex portions (18) are provided, the same effect as in the above embodiment can be obtained.

[Effect of device]

As described above, according to this invention, since the bottom surface of the air filter attaching / detaching lever is provided with a plurality of concave surfaces, the operability when attaching / detaching the air filter can be further improved.
